Title: Clock device
Inventor: YASUTAKE HIROYUKI
IPC: G04G3/02
Filed: 1986-07-11
Abstract: PURPOSE:To obtain an inexpensive and easily adjustable clock device by converting a clock reference signal into clock operation signal on the basis of an accurate calibration reference frequency signal. CONSTITUTION:When a calibration command is inputted from a key entry part to a time limiting device, a counter 13 executes the counting operation of a clock reference signal 101 having an error at the leading edge 105 of an accurate calibrating reference frequency signal 102. The counter 13 stops the counting operation at the trailing edge 106 of the signal 102 and a count value 107 of the signal 101 for one second is stored in an electrically erasable ROM 3. At the time of starting normal operation after counting the count value, i.e. a calibration value, the count value 107 stored in the ROM 3 and the signal 101 are inputted to a programmable frequency divider 14 to divide the frequency of the signals, so that an accurate clock operation signal 108 can be obtained. Thus, the inexpensive and easily adjustable clock device can be obtained.

IPC: C30B29/06
Filed: 1987-06-30
Abstract: PURPOSE:To improve distribution of an impurity concentration in a single crystal grown on the seed side of the single crystal, by applying a voltage across both ends of a hot molten part formed in the contact part of the single crystal seed with a polycrystalline rod. CONSTITUTION:In producing an Si single crystal by a floating zone (FZ) method, an anode 12 of a power source 11 is connected through an electric conductive wire 14 with a single crystal seed 9 of the lower shaft and a cathode 13 of the power source 11 is connected through the electric conductive wire 14 with a polycrystalline rod 2 of the upper shaft. The seed 9 is subsequently brought into contact with the polycrystalline rod 2 and a voltage is applied from the power source 11. In this state, the contact part of the seed 9 with the polycrystalline rod 2 is then partially melted by a high-frequency heating coil 3. The seed 9 and the polycrystalline rod 2 are subsequently rotated in the opposite directions as shown in the figure to move the coil 3 in the upward direction 10. The resultant formed molten part 6 of a given width is then moved to the polycrystalline rod 2 to grow a single crystal 1 on the side of the seed 9. Since stirring of the Si melting part 6 can be promoted by the aforementioned method, distribution of impurities in the diameter direction of the Si single crystal 1 can be improved.

IPC: G06F9/32
Filed: 1985-07-25
Abstract: PURPOSE:To perform high-speed arithmetic processing by controlling the input to a conditional arithmetic instruction control accumulator by the combinational logic of the output of an instruction decoder and the output of an ALU indicating the state of an arithmetic result. CONSTITUTION:The arithmetic circuit ALU performs arithmetic operation by using a value M from a memory and the value of the accumulator and outputs PSW as a set of the arithmetic result and signals indicating its various states. Further, a combinational logical circuit which inputs the PSW and the output of the instruction decoder and the accumulator ACC which determines whether the data is written or not with a control signal CD are provided. Consequently, the value of a memory is subtracted from the value of the accumulator; when there is a barrow, the result of the subtraction is written in the accumulator and when not, the subtraction is not performed. Consequently, the program of recovery type division by addition and subtraction is simplified to realize high-speed arithmetic.

Filed: 1985-07-26
Abstract: PURPOSE:To prevent mistakes in the operation steps by providing display lamps close to the operation sections for temperature setting arranged on the operation panel, time setting and start of cooking, and flickering successively the display lamps by selectively operating the cooking function selection switches. CONSTITUTION:After a food is placed in a heating room 2, its door 3 is closed and either one of cooking function switches 9 is pressed. Supposing a selected cooking function is 'oven', firstly a display lamp 13 flickers. Next, if the temperature in the store room is set by pushing a temperature setting button 10, the display lamp 13 is put off and further a display lamp 14 for time setting flickers. Here, when a time setting knob 11 is rotated to set time, the display lamp 14 is put off and a display lamp 15 flickers. Next, when a start of cooking button is pressed, the display lamp 15 is put off and cooking is started. If automatic cooking is selected, start of cooking button 12 is directly operated. A microcomputer 16 thus makes display lamps flicker whichever cooking function may be selected and indicates the operation steps. Mistake in operation is therefore prevented.

Filed: 1997-06-23
Abstract: PROBLEM TO BE SOLVED: To reduce the occurrence of jitter by on/off-controlling a heater selected by receiving an external selection signal with a pulse signal from a flip flop. SOLUTION: The SSR flip flop 11 generates prescribed pulse time where the pulse width of the outputted pulse signal 11Q is set to be delay quantity 20 dly from the output terminal of a delay circuit 20. A heater driving part 80 controls stepwise the heating quantity of heaters 91-9n which are individually divided with the external selection signal SEL. The heater in an active state, which adjusts and sets the calorific value of the whole circuit to be a temperature balanced state, on/off-operates. Namely, it is always turned on when a clock does not exist and it is in a heating state. Whenever it receives the pulse signal 11Q from the SR flip flop 11, heating control which is in inverse proportion to the clock frequency is executed by making it to be off during the pulse period.
